Abstract: PROBLEM TO BE SOLVED: To improve attenuation characteristics toward lower frequencies by connecting an IDT SAW resonator as an attenuation improvement SAW resonator in parallel and in cascade connection with an n-stage ladder circuit configuration section so as to form a reflector type SAW resonator without generating spurious radiation. SOLUTION: An IDT SAW resonator 103 does not have a reflector at both ends of an IDT different from a reflector type SAW resonator, but the number of pairs of the IDTs 111 is selected to be a multiple structure of 200 pairs or over, then internal reflection in the inside of the IDTs to generate a standing wave on the IDTs thereby causing the resonance. The resonator type SAW filter of n-stage of a latter configuration of the reflector type SAW resonators is formed by connecting an IDT SAW resonator 103 as the attenuation improvement SAW resonator in parallel and in cascade with the n-stage latter type circuit configuration section 101. Thus even when an electrode finger film thickness H/λ of the SAW resonator is selected about 0.08 to 0.1, the attenuation characteristics toward lower frequencies is improved without causing spurious radiation in the pass band of the filter.

Inventor: KONDO MASASHI
IPC: G01R33/34
Filed: 1993-02-25
Abstract: PURPOSE:To lower production costs and a production process significantly by forming a coil used in a magnetic resonance video apparatus by corrosion and cutting methods such as etching method to solve problems of heat generation, self-vortex and the like. CONSTITUTION:AGSC is built by an etching method. In a hybrid system combining a filling method and a coil turn multilayer separation method of a conductor part, a conductor center interval Wcdi of areas (a) and (b) and (a), Wcdi and (b), a width Wcd of a conductor and (a) and Wed and (b) are expressed by Wcdi and a=4Wwire, Wcdi and b=2Wwire, Wed and a=4Were-We and min and Wcd and b=2Wwire-We and min. Hence, in the area (a), even if the mine and Wwire are the same, the resistance lowers by about a half as compared with a double-layer parallel of the system 1. On the other hand, in the area (b), the resistance lowers significantly as compared with the double-layer parallel of the system 1 when the We and min are the same as the Wwire. But when the We and min are smaller sufficiently than the Wwire, the drop in the resistance remains the same as the system 1.

Title: Control method for water level of reservoir
Inventor: MASUI SHIYOUICHI
IPC: G05D7/06
Filed: 1980-03-24
Abstract: PURPOSE:To control the water level of a reservoir according to fluctuations of an inflow without delay by making a successive proper correction of an estimated coefficient detected on the basis of an estimated inflow value and inflow deviation at each point in time between the start point of control and current point. CONSTITUTION:Water gauge 2 detects water level Li of reservoir 1 at time (i) and sends it to water-level inflow converter 4 and optimum manipulated-variable determination device 6. Converter 4 calculates inflow, which is the difference between inflow qi and quantity li of demand, from the difference in water level between time (i) and sampling time (i-1) preceding by one point and the discharge and then inputs inflow Ri to environmental change estimation device 5. Device 5 calculates estimated values at respective points in time (i+1)-(i+m) on the basis of inflows at points in time (i)-(i-n), and then sends a column of vectors, depending upon those estimated values as elements, to device 6. Device 6 calculates discharge (ui+1) at the next sampling point from the column vectors of the estimated values and water level Li and sends it to discharge valve opening-extent converter 7. On the basis of it, converter 7 updates the opening extent output of valve 3 from (thetai) to (thetai+1) to control valve 3 via valve driver 8.

Title: High fidelity television receiver
Inventor: ICHIKAWA TEIICHI
IPC: H04N19/00
Filed: 1988-02-19
Abstract: PURPOSE:To obtain a high-picture-quality frieze picture by using the normal signal of the line corresponding to an interlace from an intra-field inserting means, preparing the auxiliary signal of the line which does not correspond to the line for a luminance signal and a chrominance signal respectively and supplying them to a mixing means. CONSTITUTION:When the frieze picture is requested, a field signal, which is taken out from an inter-frame inserting part 6, having the same capacity at any time is supplied tot he intra-frame inserting means. Consequently, even when a motion part is stored in memories 9 and 11 in the inter-frame inserting part 6, a flicker is not generated. Further, since an interlace correcting circuit 19 executes an interlace-correction for the separate interlaces by the luminance signal and the chromiance signal, even when the frieze picture is set by repeatedly using the same data, the flicker due to the interlace is not generated. Thus, the high-picture-quality frieze picture can be obtained.

Title: Flow rate control valve
Inventor: NONAKA SETSUO
IPC: G05D7/01
Filed: 1986-02-24
Abstract: PURPOSE:To prevent a valve box from being damaged by an erosion even if a jet from a small hole generates a cavitation, by curtailing the number of valve boxes of a flow rate control valve, attaching directly a cage and an inner valve to a tank, and jetting a jet from the cage into stored water in the tank. CONSTITUTION:High pressure water which has flowed in from a valve inlet 30 passes through a valve seat 23 and goes into an inside 31 of a cage 22, passes through many small holes 22a provided on the cage 22 and jets into stored water 1a of a flow rate control valve chamber 1b which has been attached to a tank 1. In case a flow rate control valve opening is an intermediate opening, a part of the small holes 22a of the cage 22 is closed by an inner valve 21, therefore, a flow rate flowing out to the tank 1 from the cage 22 decreases. However, since there is no multistage orifice, a differential pressure of the small hole of the cage is roughly constant. In this way, since an inner valve with a balance hole is used, there is an effect for reducing a driving force for a control of a large flow rate, and since a flow rate control valve 20 is provided, the installation plate and its direction can be selected freely.
